DESCRIPTION
The resistors are constructed on a
high grade ceramic body (aluminium
oxide). Internal metal electrodes are
added at each end and connected
by a resistive paste which is applied
to the top surface of the substrate.
The composition of the paste is
adjusted to give the approximate
resistance required and the value is
trimmed to within tolerance by laser
cutting of this resistive layer.
The resistive layer is covered with a
protective coating and printed with
the resistance value. Finally, the two
external end terminations are added.
To guarantee optimum solderability
the outer layer consists of a lead-tin
alloy.

FUNCTIONAL DESCRIPTION
Product characterization
Standard values of nominal
resistance are taken from the
E24/E96 series for resistors with a
tolerance of
±5%.
The values of the
E24/E96 series are in accordance
with
“IEC publication 60063”.
